Could you build this?
No Building a serverless, peer-to-peer E2EE messenger on mobile involves severe distributed systems hurdles like decentralized routing, NAT traversal, and offline message synchronization without a central authority.
What it would actually take: The application requires a robust libp2p stack (Kademlia DHT, WebRTC/QUIC, circuit relay fallback), libsodium-based end-to-end cryptographic protocols, and a store-and-forward relay mesh for offline peers. Overcoming mobile OS background execution limits and push delivery in a decentralized setting requires expert-level distributed systems and cryptographic engineering.
